How to unlock the Gas Powered achievement in Zombie Apocalypse - Definitive Guide

Day 14 is chainsaw only anyway so just play till you pass that day. Don't worry about exploding barrels as they don't interfere with the achievement.

Easiest in local multiplayer with a few friends on level 1. Use RT for the regular chainsaw attack and rotate in little circles to chop up the attacking zombies. Shake your move stick to break the grapple if you get grabbed by a zombie and try to stay away from trouble. You can only kill zombies with the chainsaw so don't shoot or throw zombie bait.

I had a lot of lag on XBox LIVE so I'd try this on local if you have friends available.

I just did it on the first stage. Even if you end up continuing you still get it as long as you only use the chainsaw.

Watch out you don't keep the right stick pressed when shaking off zombies so you do not accidentally shoot, and you can get it easiest in the first stage as mentioned above.

Keep in mind, that if you are playing through the game normally, level 14 is a "Chainsaw Only" level. You can die, and continue on this level and will still get the achievement, as you can't use anything else to kill on this level. Good for anyone who is having issues clearing a 'normal' level with only chainsaws.

I found this easiest playing solo on level 1, run around holding RT and if you do get in a big group of them just hold LT and while executing one aim for the next one and they won't harm you while you're switching. If while breaking a zombie's grapple you accidentally shoot but don't kill anyone this won't affect your achievement.

On this one, start over to Day 1 and use nothing but your chainsaw. I suggest using the standard way than the Execution way. Won't be too hard to actually do this one. Even if your online and you're just using your chainsaw, you can still get it.
